Solve using the extent of reaction e method and complete solution.
What is the concentration of A after 20.5 minutes for the reaction A → Products when the initial concentration of A is 0.800 M? (k = 0.00651 M/min)
For the following reaction set, define or propose two types of reactor systems to maximize product D selectivity, sketch the reactor system and describe clearly the input reactant concentrations and separation requirements if necessary. The unit of reaction rate is in units (mol/dm^3.sec) and concentration in units (mol/dm^3). (question on picture)
A first order reaction of the type is carried out: A ----> B And the reaction rate constant is 3.9 × 10–3 s-1. Determine the time when the concentration of reagent a will be 60% of the initial concentration.
The following irreversible reaction takes place in a batch reactor? → B Determine how long it takes for the conversion to reach 50%, if the reaction is a second order reaction with respect to A and kCA0 = 0.2 min-1,
. Our packed bed reactor runs the gas phase reaction A → R at 10 atm and 336°C, and gives 90% conversion of a pure A feed. However, the catalyst salesman guarantees that in the absence of any pore diffusion resistance our reaction will proceed on his new improved porous catalyst (De = 2 x 10-6 m³/m cat · s) with a rate given by mol -rA = 0.88C A m³ cat · s which is much better than what we now can do. The catalyst is rather expensive, since it is formulated of compressed kookaburra droppings and it is sold by weight. Still, we'll try it when we next replace our catalyst. What diameter of catalyst balls should we order?
A (eth) + B (eth) → P (s) a reaction with side reaction A (eth) + 2B (eth) = Q. P is desired product and Q is not desired. the reaction is carried out in batch operation mode, explain how shifting to semi batch will reduce amount of Q being produced while maintaing P as it is. - reaction is zero-order in both components A and B. -low selectivity(0.1%) nP= 60 mol
Q1: The dehydration of butanol is carried out over a silica-alumina catalyst at 680 K. CH,CH,CH,CH,OH-CH,CH=CHCH, +H,O The rate law is kP. (1+K,P.) with k 0.054 mol/gcat.h.atm and Keu = 0.32 atm1. Pure butanol enters a thin-tubed, packed-bed reactor at a molar flow rate of 50 kmol/hr and a pressure of 8 atm. a) What PBR catalyst weight is necessary to achieve 90% conversion in the absence of pressure drop? Plot and analyze X, and reaction rate, as a function of catalyst weight. b) What fluidized bed reactor catalyst weight is necessary to achieve 90% conversion? c) Repeat (a) when there is a pressure drop, with the pressure-drop parameter a = 0.00085 kg 1. Compare this weight with that for no pressure drop to achieve the same conversion and give your comment.
Reactant A decomposes as follows: A Rdesired S T U where n, are reaction orders. Qualitatively find what flow (plug, mixed, or inter- mediate) and what CAO (high, low, or intermediate) should be used for a high conversion to R. 11 12 из Па th Case (a) 1 1 1 1 (b) 1 2 1 1 (c) 2 1 1 1 (d) 1 2 (e) 1 (f) 1 02 21 1 0 2 1 1
